HYnRooARBoN-VAPR BURNER.'

Application led April 23, 1927, Serial No. 186,104, and n- Great Britain Mayf25, 1926.25

This invention' relates to thatv class of hydrocarbon vapor'burner having ya vapon reciprocable needle for cleaning the jet ori-l` Iice and in which the supply of liquid fuel to the vaporizing tube shall be cut ofi' vwhen y the jet orifice at the end of the vaporizing .y 7 lcan act upon-thefvalve 1() candlmove it tube-is closed by the needle or vice versa..

' The object of the present invention is to construct in an improved manner the appliances for cuttingoif the supply of petroleum or liquid fuel tothe vaporizin'gv tube when the point of the needle has entered the small orifice at the end of the vaporizing tubel to close same and vice versa, and whereby should any excess of pressure be set up in the vaporizing tube it will act upon the closure valve and openit so that the excess of pressure will pass to the container.

My invention will beJ readily understood from the construction".shown on the annexed drawings in which:-l

Figure 1 is an elevationof a vlamp of they kind in which my invention can be applied.

Figure Qis a sectional elevation of a suitable form of 'vaporizing tube, needle and opeiating mechanism with my inventionapplie Y Figure 3 is a section on the line e ar of Figure 2. Figure 4 is a -section on the line b. b of Figure 2. e

Figure 5 is a section on the line o cof FigureeQ.

According to this invention the entrance end of the fitting D is reduced in internal diameter and provided .with a portion D1 of smaller. external diameter, projecting from the fitting D with the end formed as avalve seating 6. Y

`Within the fitting'D isvpositioned a rod 7 having flutings 7l and a mushroom head 7b and normallyone end projects beyond the fitting Whilst the mushroom head 7b engages the eccentric N. y

Screwed to the Vextension D1 is atube 8 having one end perforated. as at 9, and Within the tube is a valve 10 guidedy by a stem 11 in a central perforation of the end of the tube 8 and controlled by a coiled spring 12 encircling the stem 11 to normally press the valve 10 on the seating 6 at the end of the extension D1.

The tube 8 and its appendages are preferably situate within the container E or it may be a supply pipe.

' The eccentric mechanism N operated by the turn button Q is employed for actuating thev needle J in one direction, av spring AL actuating the needle J in the other, and the` rod 7 is of such a length that, when'the eccentric N is in one positionand the needle J Withdrawn from the jet orifice O, the Irod from its seating' as at Figure 2.

f Therod 7 loosely'fits the fitting `D so that oil can passup the flutingsl 7a to thevaporizingtubeA,`and the valvel() in the tube f S'isralso a loose fit for vvthesame purpose, the f oil under pressure passing throughthe per-A forations9 1n thetube S around the valve 10 and rod 7 and up the flutings 7a tothe' v'aporizing tube A. f v

' In use when the turn button Q has been actuated to lift the needle J tO-elose the jet from the rod 7 and .the spring 12 has closedr the valve 10'on tothe seating Gand 'stopped orifice O, the eccentric Nhas lfreed itself supply of liquid fuel to the vaporizing. tube A, and on a reversal o f the' eccentric N the needle J is freed from the jet orifice and, the eccentric NA has acted upon'the rod 7 and forcedthe valve-10 from vits seating to allow liquid' fuel to pass tothe vaporizing tube. i f f 'Y I preferto mounta filter bag 13 on the l/VhatI do claim as my' invent-ion and dee sire to secure by Letters `Patent is :--r

sof

1. The combination with 'a hydrocarbon fuel supply,of av burner including a Vaporizing tube having a' jet orifice, a spring-'opened jet valve, a spring-closed fuel control valve,

` manually operated means for closing the jet` valve and permitting the fuel valve to close, and means for directing-the excess gas pressure in the'tube to automatically openv the fuel valve so that vsuch excess gas willV pass into the fuel supply. v

2. The combination with a hydrocarbon fuel supply, of a burner including a vaporizing tube having a jet orifice, a spring-opened jet valve, a spring-closed fuel control valve,

lli() a grooved rod normally engaging the fuel Valve, and manually controlled means for depressing; said rod to o en the fuel valve and permitting the jet va ve to open and for closing the jet valve and permitting the fuel valve to close, and whereby any excess pres- Y sure 1n the tube will pass around the rod to open the fuel valve supply.

3. The combination with a hydrocarbon fuel supply, of a burner including a vaporizi u g tube h aving` a jet orifice, a spring-opened jet valve, a spring-closed fuel control valve, a. manually operable :eccentric for controlling` the valves, theA jet valve when closed by the eccentric permitting the fuel valve to also close, and means whereby, when the pressure in the vapor tube overcomes that in the fuel supply, the fuel controlled valve is opened.

fl. The combination with a hydrocarbon fuel supply, of a burner includinga main carryingv body, a vvaporizing tube having a j et orifice at the upper end thereof, a springepened needle valve for 4controlling said orifice, a spring-closed fuel control valve at ythe lower end of the main body, manually to exhaust into the controlled means interposed between the two valves, whereby when the jet valve is closed i the fuel lvalve is also closed, and means when vboth valves are closed and the pressure in the vaporizing' tube is greater than that in the fuel tank, the fuel valve will be opened to admit the gas to the tank.

5. A burner including a main casing' provided with a valve seat in its lower end,

Y a. vaporiz-ing tube having a. jet orifice at the other end of the casi-ng, a spring-opened valve for the jet orifice mounted in the casingr, a Mering-closed fuel valve at the lower end of the casing," and normally *engaging the seat` and amanually controlled eccentric mounted i'n the casing for operating` the valves.

6. A'burner including; a main casing provided with a valve seat in its lower end, a

'aporizing tube having' a jet orifice at ther the latter'valve being of such strength as to permit the valve to unseat due to excess pres sure in the vaporizing' tube.

7. A burner includ-ing a main casing,r provided with a valve seat in its lower end, a vaporizing tube in the upper end and provided with a jet orifice, a spring-opened valve for the orifice mounted in the casing,

a spring-closed fuel valve at the lowerend of the casing and normally engaging the scat. a groove/d rod slidably mounted 1n the casing and normally engaging the fuel valve,

and a manually controlled eccentric disposed' between said rod and the )et valve whereby,-

of the casing. and normally engaging` the.v

scat, a groovcd rod slidably mounted in ther casing' and normally engaging the fuel valve,l and a. manually controlled eccentrilcdisposed between said rod and the jetl valve`,\vliereby, when the valveis closed, the fuel valve' is also closed, the spring of the fuel 'valve being,y of such a tension that when the pressure in the vaporizing4 tube is of sufficient strength it will open the val-,ve and' permit the escape of such pressure through the f-uel valve.

9. The combination with a'fueltank, of a burner connected thereto and having twoI spring-actuated valves, one of lthe valves being` normally opened and the other normally closed,` and selective means for closing the vnormally-opened valve and for openina' the normallyl closed valve..A

l0. The combination with a fuel tank, of a burner connected thereto and having two spring-actuated valves, one of the valves bc-` iug normally opened and the other normally closed, a vaporizing` tube having ajet orifice, the spring-opened' valve being disposed to control the orifice, andV selective means for closing the lattervalve and permitting the other valve to close, the tension of the spring of ythe last-mentioned valve being such that any excess pressure in the vaporizing tube will open said valve.

In testimony whereof my hand.
